The cup 20blank used in this type ofconical cup making machine is preferablyconstructed or prepared `paper or the like and each blank is ofsubstantially quadrantal form as illustrated in Figure 2 and is boundedby an arcuate edge 38 which eventually forms the drinking rim or edge ofa completed cup. The cup blank furthermore is houndedby j asubstantiallyv straight edge 39 one end of which connects up with thearcuate edge 38 while the, other end merges into a curved edge 40`whichforms an extension or tab 4|. 'I'he vremaining edge ofthe blankis ofcomposite form and vconsists of lan outer radial straight edge 42 and aninwardly curved edge 43 vwhich extendsfrom the inner end of the edge 42to one end of the curved vedge 40 forming the tabl. The outer' end ofthe straight edge 42 connects up-with the arcuate' edge 38 of `theblank. By providingthe blank with the composite edge 42--43 the marginsof the blank bounded by the straight edge 42 forms a gripping tab orlipwhich when a blank is advanced to the forming vmachine will enter therecess of a forming mandrel to be engaged by gripping means tofacilitate forming of the blank .into 'a cup as hereinafter more fullydescribed. One surface of the blank extension 4I and one side of themargin of the blank adjacent the straight edge 39 is adapted to beprovided with a layer or patch of cementitious material, the edge ofsaid patch of adhesive stoppingliprtof the edges 39 and 40 of the cupblank. The shape of the adhesive layer or patch applied to the cup blankis determined by the shape of a glue stamping pad hereinafter furtherdescribed.

` The cup blank feed mechanism will now be l ofa stack of blanks. Thestack of blanks is G5,

lsupported upon a pair of blank supporting arms 5I which are secured toa rocker shaft 52 which is journalled in suitable bearings afforded bythe supporting legs 46 and 41. The varms 5i thus afford a pivotalsupport for the stack of blanks to permit the sta'ck of blank.: to beraised out of feeding position when the supporting arms are swungupwardly. Y

The movement of the blank supporting arms Il, for the purpose of raisingthe stack of blanks,

ls controlled by the manual movement of a blank heater 53 which 1spivotally mounted at one end on a supporting bracket or wall 54 securedor formedon an auxiliary supporting frame 55 which is rigidly securedupon the auxiliary frame 5 as clearly' illustrated in Figures 5 and 18.The heater 53 may be heated by any suitable means such as electricheating coils or the like and is provided for the purpose of heatingblanks to permit a coating or patch of adhesive or glue to readilyadhere thereto. oted end of the heater 53 is a. roller 56 which hasrolling contact with a cam bar 51.. One end ofV the cam bar 51 ispivotally connected to the upper end of a link or togglemember 58 thelower end of which is pivotally supported on the auxiliary frame 55. Theopposite end of the cam barv 51 is pivotally connected to the upper endof a crank arm 59 the lower end of which is secured on one projectingend of the rocker shaft 52 on which the blanksupporting arms 5| aresupported.

The stack of blanks in the magazine in addition to being supported onthe supporting arms 5| are supported on a blank feed device comprising acup blank feed shaft 60. The blank feed shaft 60 is journalled inbearings formed on the magazine arms 46 and 41. Supported on the feedshaft 60 are a plurality of spaced discs 6| between each pair of which apair of diametrically opposite blank feed friction blocks or pads 62 aremounted with the pads having portions thereof projecting to engage thelowermost 'cup blank in themagazine at each half revolution of the shaft60.

Fixed on one projecting end of the blank feed shaft 60 is a gear 63which meshes with a large intermediate gear 64 which is rotatablysupported on the outer side of the magazine supporting legs 46 asclearly illustrated inFigure 18. The intermediate gear 64 is in meshwith the blank feed driving gear 25 to receive a drive therefrom.

Also secured on the blank feedshaft 6|) to the inside of the gear 63 isa gear 65 which meshes with an intermediate gear 66 fixed on a stubshaft which is journalled in the magazine supporting arm 46 as clearlyillustrated in Figure 18. The intermediate gear 66 drives a gear 61keyed on one end of a lower blankfeed roller 68 which is supported insuitable arms forming a part of the magazine framework. Meshing with thelower blank feed roller gear 6 1 is an upper blank feed roller gear 69which is secured on one end of an upper blank feed roller 10 supportedin the magazine framework above the roller 68.

The lowermost blank from the magazine is adapted to be removed from thebottom of the stack by means of the feed pads 62 and the removed blankis fed between the feed rollers 68 and 1|] which serve to advance theblank upon a blank receiving table 1| with the portion of the blankadjacent the edges 39 and 40, projecting beyond the blank supportingtable 1| and beneath the blank\heater 53 into a position to permit afilm or patch of adhesive or glue to be applied thereto by means of aglue pad 12 (Figure 20). The pad 12 is formed on the top of a gluestamping plate 13 which is mounted on the upper end of a verticallyslidable bar 14. The glue pad supporting bar 14 is slidably mounted tooperate vertically in a guide plate 15 which is rigidly supportedvtransversely in the auxiliary mounting frame 5 and is provided with anopening 16 as clearly illustrated in Figure 19. Supported in theauxiliary frame 5 is a shaftD 11 Supported on the piv-l on which ispivotally mounted a lever or arm.18 having a roller 19 rotatablysupported on one side thereof and in rolling contact with the glue padcontrol cam 24 to cause vertical reciprocation of the glue pad by meansofthe pivoted lever 18. 5 The lever 18 projects through the guide plateAopening 16 and through an opening in the glue pad supporting bar 14 andhas an adjusting mechanism connected thereto and to the slide bar 14 asclearly illustrated in Figure 19. 10

A glue applying mechanism forms a. unit of the cup making machine and isprovided for the purpose of applying glue to the glue pad 12. Referringto the detailed Figures 18, 19,l and 20 a shelf 8| ist rigidly securedupon the auxiliaryi 1 frame 5` and has supported thereon a glue tanligior trough v82. lRotatablymounted within thal tank 82 is an adhesiveapplying roller 83 which rotates in the glue within the tank. The roller83 is supported on a shaft 84 one end of which 2 projects from the tank82 and has a gear 85 mounted thereon. The gear 85 meshes with a gear 86which is rotatably supported on a stub shaft 81 supported on the shelf8|. Also mounted on the stub shaft 81 to the outside of the gear 2 86 isa small sprocket 88 around which the driving chain 21 is trained asclearly illustrated in Figure 18. An adhesive wiping roller 89 isrotatably supportedin adjustable bearing units 90 supported in the sidewalls of the glue tank 82. 3 The wiping roller 89 coacts with the gluefeed roller 83 to -wpe the excessive glue therefrom.

An adhesive transfer or applying roller 9| is mounted to be moved intorolling contact with the adhesive feed roller 83 to be supplied with acoat- 3 ing of adhesive. The roller 9| is supported on a shaft 92 theends of which are journalled in a pair lof blocks 93 slidably mountedupon a pair of guide rods 94 which are supported by arms secured to theglue tank 82 and by supports 4 fastened on the inner sides of the legsor plates 46 and 41 forming a part of the machine framework, asillustrated in Figures 19 and 20. Pivoted on each slide block 93 is aconnecting bar or link 95 the outer end of which is pivoted to the 4upper end of a crank arm 96. The two crank arms 96 are fixed on a rockershaft 91 which is journalled in bearing brackets 98 secured to one ofthe framework sills 4 as clearly illustrated in Figure 20. Also fixed onthe end of the rocker shaft 91 is a lever or crank arm 99. Projectingfrom one side of the upper end of the lever arm 99 is a pin |90 whichprojects through a slot |0| (Figure 18) provided in one end of aneccentric bar |02. The inner end of the eccentric arm |02 is 551eccentrically connected on an eccentric pin |03, projecting from theouter side of the control gear 64 which alsol governs the transmissionof a drive to the feed mechanisms forming a part of the blank holdingmagazine unit.

The above described mechanism serves to rcciprocate the adhesiveapplying roller 9| at predetermined intervals to cause the roller 9! toroll over the adhesive stamping pad 12 which is mounted upon the'stamping plate 13 and is adapted to be reciprocated at predeterminedintervals governed by the operation of the control cam 24. The glueapplying roller 9| and the glue stamping pad mechanism has theoperations thereof so timed that when the roller 9| is in a retractedposition the glue pad 12 is adapted to be advanced upwardly to stamp orapply a patch or coating of glue to the under surface of the projectingportion of a cup blank which has been advanced onto the table 1| withthe projecting 75 `which the roller ||5 is mounted is a small gear'portion of the blank positioned beneath the heater 53 which acts as astop member as well as a heating member for a blank which is beingstamped with glue.

After a blank has been moved onto the table 1| and has been stamped witha spot of glue the glued blank is next removed or moved transverselyacross the supporting table 1| in a direction substantially at rightangles to the path of movement of the blank between the blank feedmagazine and the glue applying mechanism. The glued Jiank is movedtransversely by a secondary or auxiliary blank feed mechanismcomprising' inlv part a blank pusher arm |04 having integrally formed onthe inner end thereof a yoke or fork consisting of two'pusher-ngers |05and Mit with the arm or linger |05 being slightly longer thanthe nger|36 to afford an arrangement whereby the ngers to conform to thecurvature of the arcuate edge 33 of a. blank M. The pusher ngers |35 and|35 have the ends thereof curved or bent downwardly to project throughparallel slots It'i (Figure 2).

Integrally formed on the outer end of the collar |58 is acam disc |68 having a cam notch |8| formed'therein as clearlyillustrated in Figure 13. Projecting from the inner side of the'cam disc|88 is a pin or post |62 to which one end of a coiled control spring |63is secured. The other end of' the control spring |68 is engaged on a pinor post |64 which projects through the cam notch I6| and is supported onthe free end of a control pawl |65 which is pivotally mounted on oneside of the cam disc as clearly illustrated in Figures 13 and 14.Rotatably supported on the outer side of the control pawl is a roller|88'which coacts with a short bellcrank arm |61 having a To facilitateexplaining of the operation of the cup forming unit the various mandrelsforming a part thereof are adapted to be carried through successivepositions from the position or station A to intermediate stations B andC and finally to a cup discharge station D. The various stations .justmentioned are clearly illustratedin Figures 6 and 8 of the drawings. Thecontrol gearsegment |88 is in coacting or meshing engagement with a gearsegment |1| forming an integral part of a control cam or arm |12 whichis pivotally mounted on the disc |88 as clearly illustrated in Figure13. The gear segment control arm |12 is so positioned that the outer endthereof projects beyond the periphery of the disc |68 to serve as ameans for controlling the opening of the gripper mechanisms of theforming mandrels tovpermit release of a finished container or cup at apredetermined time in the operation of the machine. The gripper openingcontrol cam arm |12 during the rotation and translation:` of each of thecontainer or cup mandrel unitsvisbrought into contact with a stationaryblock or boss |13 which is rigidly secured to the rear upper portion ofthe turret wheel housing |58 as clearly illustratcd in As clearlyillustrated in Figure 13 the control bell-crank imit |81|88 is keyed orotherwise secured on a projecting portion of a gripper control sleeve orstem |14 which projects through and is rotatable in the spindle orsleeve |51 as clearly illustrated in Figure 1l.

The front end of the gripper control sleeve |14 projects outwardlybeyond the front end of the spindle or sleeve |51 into a chamberedconical container or cup forming mandrel |15 which is rigidly secured tobe rotated with the spindle |51.4 Each of the cup forming mandrels |15is provided with a gripper chamber 16 and with an external. groove orrecess |11 provided in the enlarged exterior portion of the formingmandrel for the reception of the gripping-margin or flange of a cupblank as hereinafter more fully described.

Secured by means of a pin or key |18 (Figure 12) on the end of thegripper control sleeve |14 which projects into the chamber |16 of themandrel is a gripper collar or sleeve |18 having a thereon.

Each of the gripper control sleeves 14 is provided with a compressed airoutlet passage |8| which communicates with a main air outlet chamber 82provided in the mandrel. As clearly illustrated in Figure 171 each ofthe mandrels is provided with a plurality of auxiliary air outlet es |88which extend from the main outlet e |82 outwardly through'the exteriorsurface of the mandrel a short distance from the apex thereof.

For the purpose -of discharging or removing a completed container or cupfrom one of the forming mandrels |15 when the saine reaches thedischarge position D a compressed air discharge unit is supported on thetop of the bracket |56 as illustrated in Figures/11 and 16. Secured onthe rear projecting end of each of the passaged gripper control sleeves|14 is a flanged head or collar |84. Integrally formed on the upper endof the bracket |56 is a sleeve |85 having an axial air passage |88provided therein. A flanged head 75 -2|| secured to the front face ofthe turret wheel |01 is integrally formed on one end of the sleeve |85and said flanged head is provided with va recess |88 (Figure 11) inwhich the passaged shank |89 of an adjustable air coupler |90 isslidably engaged. The air coupler head |90 is rounded as illustrated inFigure 11 and is adapted to be normally'held resiliently projectedbymeans of coiled springs |9| which are seated in suitable pocketsprovided in the flanged head |01 with said springs being engaged aroundslidable stems |92 having heads provided on the outer ends thereof forthe purpose of limiting the outward movement of the coupler head ESQ.

It will thusbe noted that when a forming mandrel unit of the cup formingmachine is moved into position D into alignment with the air supplysleeve m that the anged head |343 rst causes the spring controlledcoupler is@ to be depressed to permit the rounded head of the coupler|90 to have a tight resilient contact with the hanged end of the head|86 so that the mandrei unit when reaching the position D is adapted tobe positioned in alignment with the compressed air unit to allow acharge of compressed air at a predetermined time to bev admitted intothe mandrel |15 and the chamber |82 thereof so that a plurality ofcharges of compressed air are .adapted to be emitted through the outletpassages |83 to cause a completed container or cup to be blown off ofthe mandrel at the time the gripper mechanisms of the mandrel arereleased.

Connected in the outer end of the sleeve |85 is an air pipe |93 on theouter end of which an air valve unit 19d is secured. A compressed airsupply pipe |95 is connected with the upper end of the valve unit iSd topermit a charge of compressed ar to be admitted to the machine from anysuitable source of air supply. Secured to the exterior of the casing` ofthe valve unit lst is a downwardly projecting bracket or arm |96 (Figure16) on the lower end of which an arm or beam |91 is fulcrumedintermediate its ends. One end of the beam |91 is pivotally connected tothe lower projecting end of a, valve stern |98 which controls theoperation oi the air valve within the air valve unit |94'. Pivotallyconnected to the opposite end of the fulcrumed beam |91 is the upper endof a connecting bar or rod ld the lower end of which is pivotallyconnected to a crank arm 20d 'which is securedl on a rocker shaft 26|mounted in suitable bearing brackets secured to the machine frameworkrear sill l as clearly illustrated in Figure l. Also secured to therocker shaft 2M is a crank arm 202 (Figure 5) to which the lower end ofa connecting rod 203 is pivotally connected. The upper end of theconnecting rod 203 is pivotally connected to abellcrank 204 which ispivotally mounted on a bracket 205 secured to the rear framework sill 4.Rotatably supported on the bellcrank 204 is a roller 206 which hasrolling contact with the periphery ,of a compresed air control cam 201.The compressed air controlf'cam 201 is keyed or otherwise secured on oneend of a shaft 208 which is journalled in the brackets 46 and 41 onwhich they Y drels |15 is a conical presser roll 209 which is rotatablysupported in va crank arm 2 |0 secured on one .end of a rocker shaftjournalled in a bearing |49 (Figure 6). Secured to the opposite end ofthe rocker shaft which is journalled in the bearing 2|| is a crank arm2| 2 having an enlarged portion or head at the outer end thereof.

of a plunger rod 2|3 which slidably projects through the turret wheel|49 adjacent the hub section thereof and has rotatably mounted in theforked rear end thereof a beveled roller 2id. As

clearly illustrated in Figures 6 and 1l there are four presser rollers209 provided, one associated with each of the container or cup formingmandrels |15. The pivotally supported presser rolls 2d@ due to theactlon'of a control cam 2lb are held iu' rolling contact with the outersurfaces of the conical cup forming mandrels. For the purpose of raisingor swinging a rotatable presser roll 209 upwardly out of rolling contactwith" a container or cup being formed on a forming mandrei when theforming mandrel is in the discharge position D the stationary presserroll control cam 2lb is keyed or otherwise secured on the hub or bearingsleeve of the bracket |56 adjacent the stationary control cam |10 asclearly illustrated in Figures '1 and 11. The presser roll control camThe crank arm 2 I2 is adapted to be pivoted by means 2|t is so shapedthat the presser rolls are norof forming the same to cause the adhesiveon the blank to more securely hold the overlapping portions of the blanksecured together a stationary presser unit is provided in the path oftravel of the cup forming mandrels. The stationary presser unitcomprises a wheel segment 2|@ the hub portion of which is keyed orotherwise rigidly secured on the front projecting Vend oi the turretwheel supporting shaft i555 as clearly illustrated in Figures 6 and 11of the drawings. The sta tionary wheel segment 2 le includes a beveledrim 2|? having a pad of resilient or ilegible material secured thereto.The exible presser pad B as illustrated in Figure 6 extends fromsubstantially the position'B to within a short distance of posi-` tion Dso that as the cup forming mandrels are translated from' one positiontcanother by the rotatable turret wheel the cups which are being formed onthe mandrels are pressed not only by the rotatable pressers 2tlg but arealso rolled over the resilient stationary presser pad 2|@ so that theglued overlapping portions of the blank forming the cup are suiiicientlypressed together before reaching the discharge position D to insurecompletion of the containers or cups Iwithout any danger of the gluedportions opening up.

'The operation is as follows:

In view of the fact that a somewhat detailed description of thevoperation of the respective mechanisms comprising the rotary type ofconicalcup forming machine has already been given in connection with thedetaileddescriptions of the various auxiliary mechanisms a brief resumof the operation of 'the machine embracing the embodiment illustratedand described will now be given.

The machine is `adapted to be started by shifting or operating thecontrol or starting lever |4 to cause the starting clutch unit I3 to bemoved into 8 i Y anni? coacting relationwith the clutch unit 3 (Figure3) sothatadrivefromthemaindriving shaft |2 is transmitted to the drivinggear 26 and the auxiliary driving gear 2| to cause rotation of the .5auxiliary driving shaft 22.

A stack of cup blanks 44 are engaged in the supply magazine between theguide postv 56 with the lowermost blank positioned to rest upon therocker arms 5| above the feeding roller 6| which is lo operated by thegear trains 25, 64, and 63. With the gears 85, 66, 61, and 69 as clearlyillustrated in Figure 18. The rollers 68 and 18 advance the blank ontothe table 1| into a position wherein the advanced end of the blanknamely. the portions bounded by the edges' 33 and 48 is advanced beyondthe outer edge of said table and beneath the heater 53 and above theglue applying pad 12. The glue-applying mechanisms are operated by thechain 21 causing the largeA feed roller 83 to 'carry glue upwardly fromthe tank 82 with the wiping roller 88 acting to remove surplus glue fromsaid supply roller. The adhesive or glue'applying roller 8| is adaptedto be'moved into roll-- V ing contact with the supply roller 63 due tothe A reciprocating motion of the arms or connecting bars 95 which areactuated from the gear 64 through the connecting bar |82 and the arms 86and 96. A coating of glue is thus applied or received by the glueapplying roller 3| from the glue feed roller 83. The roller 8| afterbeing supplied with a coating of glue is moved away from the supplyroller 33 and rolls over the stamping pad 12 to coat the same with alayer of glue.

lo The glue stamping control cam 24 at this stage in the operation actson the roller 13 (Hg.

19) to cause the lever arm 16 to swing upwardly thereby causing the glueapplying pad 12 to be elevated or pushed upwardly into contact with theunder surface of the projecting margin of the cup blank on the table 1|to stamp a patch or coating of glue on theblank as it is pressed againstthe bottom surface of the heater 53 which serves not only as a stopplate for the blank during the glue applying operation but also acts asa means for heating the glue to prevent premature drying of the gluebefore the adhesived blank is fed to the forming unit ofthe machine.After a blank has been stamped with a patch of glue theauxiliaryfeedcontrol cam |3 acting on the roller ||2(1i'!|g advancingthe glued blank into the field of operation vof the upper auxiliary feedrollers ||4 and y ||5 and-the lower feed rollers ||6 and ||1 which areoperated from the shaft 84 of the glue supply roller 83 through themedium of the beveled gears |32 and |33 (Figure 5) the chain |28 and thegear trains las-m. The auxiliary reed mixers ||4| I1 engage th'e gluedblank and advance the same from the table 1| ontothe table extension |34with the straight edge 38 of the, glued blank slidably moving along theguide arm |36 to maintain the blank in proper position as it is beingadvanced toward the cup forming unit of the machine. The glued blank isadvanced onto the table extension- |34 until the arcuate edge of the 5blank is positioned part way over the table openings |3l to center theglued blank by means of the curved end of the guide arm |36 (Figure 2)and holding arm or finger |31 beneath which the glued 'blank isadvanced. -The adhesived cup 10 blank 44 is advanced over the tableextension |34 while the retaining arm |31 is maintained in an elevatedposition by means of the control disc |42 and the roller |4| which hasrolling Acontact with the periphery of said disc. When the ad 15 hesivedblank is in the proper position to be fed to one of the forming mandrelsin position A the notch |43 'of the disc |42 reaches the position of theroller |4| thereby .permitting the roller to drop into said notchwhereby the retaining arm 20- |31 is lowered into contact withithe topsurface of the advanced blank 44 to hold theI same in proper centeredposition as the feed control cam 23,;rcoacting with the roller |48(Figure 5) causes the iingers |44 to swing outwardly through the 25table extension openings |35 to cause the lingers |44 to engage thearcuate edge 38 of the glued blank to push the blank 44 so that thegripping margin adjacent the inclined edge 42 of the blank is pushedinto the opening |16 of a forming man- 30 .dr'el |15 lwhen in the blankreceiving position A in which position the gripper |66 is in the opendotted line position of Figure l2 to permit the gripping margin of theblank to be pushed beneath the gripper ready to be engaged thereby. 35

With the glued blank properly centered as illusitrated in Figure 2 withthe margin adjacent the edge 42 projecting into a forming mandrel |15 inposition A the gripper control mechanisms are brought into operation asthe gear segment arm 40 |63 of the cup forming mandrel unit advancingtoward pomtion A is brought into coacting en-` gagement with thestationary control cam |11 (Figure 8) to cause the arm |66 to be movedfrom a 'position similar to that .illustrated in position 45 D of themandrel into a position corresponding to that illustrated in pomtion Awherein the gripper control cam |61 is positioned to one side of thecontrol miler |66 to cause rotation of the gripper control sleeve |14(Figure l1) to rock the y50 gripper collar |16 to moveV the blankgripper from the dotted line position of Figure 12 into the full linegripping'position of said ligure to cause the margin 42 of the blankprojecting into the opening of the mandrel to be gripped readyto 55 havethe blank formed into a cup.

y When theimachine is in operationthe turretI wheel |46 is continuouslyrotated ata variable speed controlled by the eccentric discsv 33 and 31which connect the auxiliary driving shaft 22 with 60 the shaft 3| bymeans of the block 34 and the guide bars 36 in the arrangementillustrated in 9 and l0 of the drawings. The variable v speed isvtransmitted from the shaft 3| to thel spiral gear 38 which is in meshingengagement 654 with the `turret wheel gear |52 whereby the turret wheelis caused to rotate at a variable' speed to cause slowing up of therotation of the .turret wheel at each quarter rotation of the turretwheel as the rotatable mandrels pass through the posi- 70 tions A, B, C,and D'to permit a glued blank to be fed to a mandrel in position A whilea completed cup on a mandrel in position D is released and dischargedfrom 'the machine. l With the continuous .rotation of the turret 76wheelA at a variable speeds mandrel |15 as if. is

advanced from station to station is rotated by internal lgear |54.

beneath the rotatable presser roll` 209 coacting with said mandrel.As'the glued blank is wound ound the mandrel the glued marginoverlaps y-a portion of the body section of the blank to form a glued seam whilethe glued surface of the tab 4| of the blank is spirally wound aroundthe apex portion of the cup under` construction thereby reinforcing theapex end of the conical container or cup. 'The rotatable pressing roller209 serves to press the glued margin of the blank asthe blank isfbeingformed into a cup and is advanced -from position A through positionsBand C toward the discharge position D. As .the cup is beingformed andadvanced through thevarious positions the flap or margin 42 of the blankis positioned on the inside of the cup body and is y engaged bythegripper |80. During'the course of travel of a'cup through the variouspositions the cup is brou ht into contact with theresilient presser. pad2| -which is mounted'on the stationwheel segment rim 2|1 wherebyadditional- 3." pressing or ironing of the cup under construction is peormed to insure proper adhesion of the overlapping portions of the cupblank.

The continuous rotation of the turret wheel carries the ironed orpressed cup toward position 35 D thereby bringing the presser rollercontrol` swung outwardly away from the completed cup engagedon theforming mandrel.

' 45 As a completed cup is carried by a mandrel into the position D thegrippe'r release control armv|12 is carried into coacting engagementwith the stationary control boss or block |13 (Figure 8) to causepivotal swinging of the control arm ,a :51)v |12 from the positionillustrated in position C of Figure 8 into the gripper releasepositionof said control arm |12 as illustrated in position D. This pivotalswinging of the control arm |12 causesthe gear segment |1| to coact withthe oo'gear segment |68 to move the gripper control -cam o'r projection|61 to cause rotation of the gripper control sleeve |14 thereby causingthe gripper |80 to be moved from the closed full line positionillustrated in Figure l2 into the dotted open line position of said'gurethereby releasing the gripped margin 42 positioned on the inside of Ythe formed cup. 'I he spring controlled pawl arm |65 has the roller |66thereof coacting with the cam or projection |61-of the control arm |69to resiliently hold the gripper |80 in gripping engagement with themargin 42 ofv a cup blank so that the gripper is adapted to be actuatedwith a snappy action at predetermined times rto either grip a up blankor release the gripped margin of acompleted cup. l As a mandrel lisadvanced nto the discharge position D the head |84 (Figure 11,) on therear end of the'grlpper control sleeve |14 is brought means ofthe gear|59` coacting with the large Y The gripped blank which is' 5 engaged bythe gripper |80v of the mandrel when in position A is drawn off of thetable 'etension v |34 and with the axial rotation `of the mandrelsaidgripper blank is wound around themandrel unitgthereb'y'causing thepassaged head |90 to be depressed to permit the mandrel unitV to bebrought into axial alignment with'the cgom-fpressed air discharge unitas clearly illustrated in Figure llwhenthe air passage |86 is'aligned lswith the air passage |81. At this stagein the operation the compressedair control camA 201 (Figure 5) actuates the bellcrank Y2 04 whichv ine' turn operates the members 203 and 202 to cause the rocker shaft 20|to be partly rotated to operate the crank arm 200 which in turn actuatesthe connecting link |99. and the fulcrumed beam |91 to cause thecompressed airvalve within the valve housing |94 to'be opened to permita charge of compressed air from the supplypipe |95 to be 15? admittedinto the vpassage |86 and the passage `|8| thereby admitting the chargeof compressed air into the mandrel chamber |82V from which thecompressed air is permitted to escape through the outlet passages |83 tostrike against the in-20 terior of the released cup to blow the cup fromthe mandrel.

As a cup is being released and discharged .from a mandrel in positionD'another adhesived cup Y blank is fed to a mandrel lin vposition A tobe 25 gripped bythe gripper mechanisms ofsaid manadrel so `that with thecontinuous rotation of the 'variable speed turret wheel a plurality ofcups aresimultaneously under process of construction so that with thefour mandrel arrangement dis- 30 closed a completed 'cup is dischargedat each quarter revolution of the turret wheel while an additional gluedblank is fed to a mandrel in position A of the turret wheel.
